The improvements made for the SwiftUI List, as presented at WWDC, include significant performance enhancements. On macOS, lists with over 100,000 items now load six times faster and update up to 16 times faster. These improvements extend to all platforms, enhancing the experience for users when viewing, filtering, or updating lists. Incremental changes, such as inserting new items, are also up to 16 times faster, and larger lists see even bigger performance gains. These updates represent a substantial step forward in SwiftUI's scrolling performance, making apps feel faster and more responsive.
